Edit tv_out.ini to override the default values for:
- the text name of the desktop shortcut (default: TV_OUT )
- the text displayed when hovering over the shortcut
(default: only PC is active / PC and TV are active)
- the location of the shortcut (default: desktop)
- only enable, never disable, second display (default: toggle)
- make a ctrl+alt+__ hotkey (default: no hotkey)
- icon 1 & 2
tv_out is a replacement for this manual procedure: right click desktop, select "properties", in display properties, goto settings tab, click checkbox to turn extended desktop on/off

If tv_out does not work on you system, it may be because your display device name varies from the one tv_out uses. See the autohotkey forum thread above for more details on how to get your device name. You can then change it in the tv_out.ahk source and compile a version that works for you. tv_out uses the device name \\.\DISPLAY2 .
